class_docstr: Optimizer used to find optimal points of cost model
docstr: Find maximum of a cost model
  
  Note we use cost model to predict GFLOPS, so we should find the maximum
  
  Parameters
  ----------
  model: CostModel
      Cost model
  num: int
      The number of returned maximum points
  exclusive: set, optional
      The excluded set of this optimizer. Return results won't include any
      elements in this set.
